Ghana's Interest Rate Cycle: What Comes Next?

Ghana entered 2026 with inflation falling from an extraordinary peak, a currency that had stabilised after a disorderly period, and a policy rate that had been held at restrictive levels for long enough to do real damage to credit growth. The question facing investors is no longer whether the Bank of Ghana will ease — it has already begun — but how far the cycle can run, and what it means for money currently sitting in short-dated Treasury bills.

That question matters more in Ghana than in most markets, for a structural reason. A large share of Ghanaian household and institutional savings sits in 91-day and 182-day Treasury paper. When the policy rate falls, those holdings do not fall in value; they simply mature into a lower-yielding environment. The risk is not a loss. It is that the return available on reinvestment is materially lower than the return investors have grown used to.

Disinflation has broadened#

The distinction between headline and core inflation is the analytical crux of this outlook. Headline inflation responds to food and fuel prices, which are volatile and largely outside the reach of monetary policy. Core inflation strips those out and is the better guide to whether price pressures are genuinely receding through the economy.

In the previous disinflation, headline fell while core did not. That divergence was the reason the improvement did not last: the underlying inflationary impulse was intact, and when food and energy prices stopped falling, headline inflation resumed its climb. The current data does not show that divergence. Core has fallen alongside headline over successive prints, which is what gives the Monetary Policy Committee room to act with some confidence.

The market has run ahead of the Committee#

Treasury auction results tell us what investors expect, not what they hope. When the yield on 91-day paper falls by more than the policy rate has been cut, the market is pricing further cuts. That is broadly what the auction data has been showing.

This has a practical consequence that is easy to miss. An investor who buys a 91-day bill at a yield that already embeds expected easing is not being compensated for the easing that has been priced. They are being compensated only for the risk that easing does not happen. If the cycle plays out as the market expects, that investor will roll into successively lower yields. If it stalls, they will be pleased. This is a materially different risk profile from the one most short-dated holders believe they have.

Pass-through to deposit rates will disappoint savers#

Here the Ghanaian evidence is unambiguous and worth stating plainly, because it affects far more people than the Treasury market does.

When the Bank of Ghana raises rates, commercial bank lending rates follow fairly promptly. When it cuts, deposit rates follow slowly, partially, and sometimes barely at all. The historical relationship suggests well under half of any policy rate cut reaches deposit rates, with a lag of two to three quarters.

For a household comparing a savings account to a Treasury bill, this asymmetry is the whole ballgame. In an easing cycle, the gap between what the government pays a saver and what a bank pays a saver tends to widen in the government's favour — even as both nominal rates fall.

The implications differ sharply by asset class, and by the time horizon of the holder.

Fixed income. The reinvestment question dominates. Investors rolling short-dated paper in a falling rate environment face progressively lower yields; those who extended duration earlier in the cycle have already captured much of the available benefit. Whether extending duration now is sensible depends entirely on whether the remaining expected easing is already in the price — and on the auction evidence, much of it is.

Equities. Lower rates reduce the return available on the risk-free alternative, which historically has coincided with increased interest in GSE equities. The mechanism is real but the effect is neither automatic nor quick, and it does nothing for the underlying earnings quality of any individual company. Ghana's listed banks in particular face a margin question in an easing cycle that the rate environment alone does not resolve.

Cash. Cash held for genuine liquidity purposes is unaffected by this analysis. Cash held as a return-seeking position becomes progressively less productive as the cycle runs — which is a reason to be clear about which of the two any given balance actually is.

Currencies. A narrowing interest rate differential reduces the carry available on cedi assets. This is one of the channels through which an easing cycle can put pressure on the currency, and is why the FX outlook is not separable from the rates outlook.

Businesses. Lower borrowing costs improve the arithmetic of capital investment, but the transmission to actual lending rates is slow, and credit availability in Ghana has been constrained by bank balance sheet repair as much as by the price of money.

We would revise this outlook materially on any of the following.

A renewed depreciation of the cedi of a magnitude that feeds visibly into the import basket would re-import inflation and, on the Bank of Ghana's past behaviour, stop the cycle. This is the single most likely route to being wrong.

Evidence that the disinflation is narrower than it appears — for example, a material upward revision to core inflation, or a divergence between the core measure and services prices — would suggest the improvement is less durable than we judge it to be.

A widening domestic financing requirement would push yields up regardless of the policy rate, because the Treasury's issuance need is a supply factor that monetary policy does not control.

Disinflation in Ghana is real and, on the core measure, broader than in the previous episode. That supports a continued easing cycle. But the cycle should be expected to end at a policy rate well above pre-2022 norms, because the fiscal financing requirement that underpins domestic yields has not been resolved, and the market has already priced a substantial part of the easing that remains.

For investors, the practical consequence is that the question worth asking is not "will rates fall?" but "what is my money going to earn when this bill matures, and is that still enough for what I need it to do?" That is a question about reinvestment and about real, after-inflation return — and it is the one most short-dated holders in Ghana are not currently asking.
